Today I Learned: Japan’s shrinking line of succession puts Prince Hisahito under huge pressure.
Prince Hisahito, just 19, is one of the last male heirs to Japan’s 2,000-year monarchy.
He recently took part in a rare coming-of-age ceremony, wearing traditional court attire with a silk crown, marking his formal step into adulthood.
He is the first male royal in about 40 years to reach this milestone.
With no brothers and only three eligible male heirs in total, the Imperial line is very thin.
Japan’s succession law allows only males from the male line, so there is no easy backup.
Polls show around 70% of Japanese citizens support allowing a female emperor, yet reforms keep stalling.
A former Imperial Household Agency chief, Shingo Haketa, has warned that Prince Hisahito now carries the fate of the Imperial Family largely on his own.
If nothing changes, the world’s oldest continuous monarchy could face a quiet crisis.
